Abstract

La présente invention concerne une alimentation électrique de commutateur à transfert indirect. Sur la base d'une alimentation électrique de commutateur à transfert indirect d'absorption à trois enroulements commune, connecter NP1 bornes hétéronymes dans un transformateur B à une source d'alimentation, et mettre à la terre NP2 extrémités hétéronymes de seconds enroulements côté primaire, en garantissant que NP1 et NP2 sont des enroulements parallèles à deux fils, ajouter un condensateur (C1), une extrémité de C1 étant connectée à NP1 bornes homonymes, et l'autre extrémité étant connectée à NP2 bornes homonymes, l'enroulement côté secondaire utilisant un procédé de connexion (Q2) qui est l'opposé de l'état de la technique, et étant commandé par un signal PWM commandé par une autre tension de sortie, moyennant quoi : lorsque Q1 est connecté, NP1 et NP2 sont tous deux excités, et il y a une énergie excédentaire artificielle; lorsque Q1 est déconnecté, le côté secondaire NS met en œuvre une tension de sortie redressée par l'intermédiaire de Q2 sur la base des exigences de charge de sortie, et l'inductance de fuite et l'énergie excédentaire sont absorbées de manière non destructive par NP2 par l'intermédiaire de D1, convenant ainsi à un fonctionnement à basse tension, améliorant le taux d'utilisation et la densité de courant de l'enroulement côté primaire, de telle sorte que la densité de courant est élevée, permettant à la fuite entre les côtés primaire et secondaire d'être relativement grande, et ayant une efficacité de conversion élevée, une bonne EMI, une alimentation électrique à large bande passante et une bonne réponse en boucle.
